To deploy qt application or harder QML app you need a tool called windeployqt availible in
C:\Qt\Qt5.7.0\5.7\mingw53_32\bin or something like that. To get start open a cmd there and add QtBin path to your enviroment PATH variable.
$windeployqt --qmldir I:\Home\Projects\AllegroAss\UI I:\Home\Projects\AllegroAss\Sources I:\Home\Projects\AllegroAss\Sources\release
Add some icon, spice (winpthread libgcc_s_dw2-1 and libstdc++-6) and you are done.
